The accident happened on south bound Malibu Canyon Road, in Malibu, California. It happened at around 9 pm yesterday. Gibson was not hurt.
He was alone in the car and police said that alcohol was not a factor of the crash.
A friend of the 54-year old actor-director picked him up from the place of event.
California Highway Patrol reported: “For unknown reasons, Mr. Gibson steered his car to the right and struck the rock hillside. He stopped his car at the scene and was contacted by officers from the West Valley CHP Area.”
Officer Leland Tang said that Mel was alone in car and was not neither under drugs nor alcohol, but was baffled as to what had gone on.
He said: “Gibson told officers in the field he did not know how the car drifted out of the lane and into the hillside.
“It was totally an unintentional act.”
The crash is the latest controversy in Gibson’s life as he is currently being investigated by police following claims he abused ex-girlfriend Oksana Grigorieva, mother of his nine-month-old daughter Lucia.
